IMPROVEMENT IN COTTON-GINS.

Specification forming part of Letters Patent No. 215,676, dated May 20,1879; application filed February 24, 1879.

To all whom t may concern:

BeitthatknownthatI,W1LLrAM SREEDER, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inCotton-Gills, of which the following is a full, clear, and exactdescription, reference being had to the accompanyingdrawings, formingpart of this specification.

The first part of my improvement relates to the driving connectionbetween the saw-shaft and the brush-shaft. This, so far as my knowledgeextends, has always heretofore consisted of a crossed belt. Thisconnection is objectionable for two reasons: First, it does not give apositive motion to the brush-shaft, and, second, the slipping of thebelt is liable to generate electricity, and the electric sparks may setre to the finely-divided vegetable fiber and dust loading the air aroundthe gin.

My improvement consists in combining, with the saw and brush shafts of acotton-gin, spurwheels which engage and cause the positive motion of thebrush-shaft from the saw-shaft.

My invention also consists in providing one of the spur-wheels withwooden cogs, so that there shall be no contact of metal with metal. Thisis to avoid the possibility of striking re, owing to the presence ofgritty dust, which is always present in the air when cotton is underginning or cleaning treatment.

'My improvement also consists in the connection of the wooden-toothedwheel, and consists in casting the frame of the wheel with recesses inits periphery, each recess being large enough to receive the shank oftwo or more teeth, which are tted in side by side, and held in by ascrewbolt, as more fully set forth hereinafter.

In the drawings, Figure l is a side view of the drive-wheel and followeror pinion. Fig. 2 is an enlarged view of a portion of the drivewheel,with part in section to show the construction.

Iart of the frame of the gin is shown atA but this forms no novelfeature o the invention. B is the saw-shaft, carrying a spurwheel, C,which engages and propels the pinion D upon the brush-shaft E. Thepinion D has the ordinary metal cogs; but the cogs C of the wheel C areof wood, for the purpose before stated.

I do not claim, broadly, the combination of a wooden-toothed wheel witha metal-toothed wheel or pinion, for this is an old arrangement inmechanism 5 but in the present case it performs 'a new function and hasspecial value.

I will now describe the Special construction of the wheel C, whichconstitutes the second part of my invention. This has a usual hub, c,and spokes cl. Its rim is divided into sockets c2, to receive thetooth-blocks F. These sockets are made in frusto-pyramidal form, withtheir larger ends open to the periphery. Each socket is formed toreceive two teethblocks, F F, side by side, as shown.

The blocks are held firmly in thesocket by a radial bolt, G, whose headg and shank gl are halved into the proximate sides of the two blocks F.The screw end of the bolt extends through the bottom c3 of the Socketc2, and is fitted with a nut, g2. Thus, by the bolt-head and nut, thetwo teeth-blocks are held in their socket.

It will be seen that this structure provides means for the easy repairof the wheel, as the teeth may be removed when worn by merely takingoli' the nut g2 andloosening them in the socket.

It will also be'seen that while the nut is screwed fastthe teethcannotmovein the Socket.

Supposing the shrinkage of the block Should make them loose in thesockets, they may be readily made tight by removing them and theintroduction of shims of paper, sheet metal, or wood.

I am aware that it is not new to construct wheels of various kinds withWooden cog-teeth. I am also aware that it is not new to fasten suchteeth in the wheel singly by means of wedges and other fastenings. Suchfeatures I therefore do not claim, broadly; but

What I claim, and desire to secure by LetA ters Patent, is

l. The combination, with the saw-shaft B and brush-shaft E of acotton-gin, of the spurd wheel C and spur-pinion D, for connecting thetwo shafts together, as and for the purpose set forth.

2. The combination7 in a oottolrgin, of the and the retaining-bolt G,substantially as set wooden-oogged Wheel C upon the saw-shaft, forth.and the pinion D upon the brushsha-ft, en- I gauging therewith7substantially as set forth.
